[Ultrasonography of echinococcosis, toxocariasis and cysticercosis of the liver].

The diagnosis of tissue parasitoses has remained complicated until the present time for variability of clinical picture. Their incidence been increasing due to aimed and accidental findings of foci in parenchymal organs employing new methods of visualization such as computer tomography and especially ultrasonography whose advantage is a good detection rate, availability and a possibility to follow the dynamics of parasitosis development. The authors present a survey of ultra-sonographic findings of the liver in cases of tissue parasitoses occurring in Czechoslovakia, while using their own image documentation. If a focal affection in the liver is established the differential diagnosis considerations should also take into account a tissue parasitosis, whose ultrasound picture may be nonspecific.
